CULINARY VESSEL.

SPECIFICATION forming part of Letters Patent No. 752,167, dated February 16, 1904. Application filed January 5, 1903. Serial h o. 137,980. (No model.)

' below a predetermined level; and the invention consists in providing at one side of the vessel a straight tube open at the two ends in line with its bore and with the opening at the lower end within the vessel near its bottom and the one at the upper end within the circle bounding the rim of the cover, and also with a small opening into this straight tube near its upper end, but below the annular waterseal channel around the upper edge of the vessel, and, further, in providing means upon the cover to closely fit the upper end of the tube and close it when the cover is properly in place upon the vessel. Heretofore in the construction of vessels of this class in which what may be termeda telltale-tube was used such tubes were open at the upper end outside of the vessel, and at or near the lower end an opening was made into the vessel substantially at right angles to the tube. With this prior construction of vessels with telltaletubes many articles of food which when cooked in the vessel become broken and disintegrated would find their way into the lower end of the tube and clog it, if not entirely stop it, and when this occurred it was with great difiiculty that the tube was freed from obstruction, because of the crook or angle therein. This objection is entirely overcome by my improved construction, as the tube is straight and open at both ends, which permits it to be readily cleared of obstructions, and it is closed at the top only when the cover is placed on the vessel, and when thus closed low Water in the vessel is indicated by the escape of steam from the small aperture into the tube just below the water-seal channel at the upper edge of the vessel.

In the drawings forming a part of this specification, Figure 1 is a vertical section of the improved culinary vessel through both tubes therein. Fig. 2 is a plan of the vessel with the cover removed. Fig. 3 is a detail illustrating.

an alternative form of means upon the cover for closing the upper end of the telltale-tube. Referring to the drawings by reference-letters, V is the vessel, provided with a rim R around its upper edge, which forms the waterseal channel S.

O is the odor-tube, and T the telltale-tube,

. with openings at the two ends, which openings are in line with the bore of the tube.

H is a small outlet in the tube T just beneath the rim R for the escape of steam whenever the level of the water in the vessel is below the bottom of the tube T. i

C is the cover, having a downwardly-projecting edge E, which fits into the channel S when the cover is properly in place upon the vessel, and thus forms a water seal. The top of the tube T may be partially cut away upon the outer edge, as shownin Fig. l, and depressions d' be made in the cover to fit over and into the tube for the purpose of closing its upper end, or the top of the tube may be made even and a flat annular ledge F formed in the cover to fit upon and close the tube when the cover is in place, as shown in Fig. 3.

It will be seen that when the cover is removed from the vessel there is a free straight passage through the tube T, and if any substance has entered the bottom of the tube it can readily be removed by a wire or small stick, and when the cover is in place the upper end of the tube is closed, so that neither water nor steam can enter at the top, and as soon .as

terminates Within the vessel near its bottom and the upper end thereof near the top of the vessel Within the circle bounding the rim of the cover, and a cover provided with means to fit over and close the upper end of the passage when the cover is in proper position upon the Vessel.

2. In a culinary vessel provided with an annular channel around its upper edge adapted to retain liquid a straight tube or passage With open ends and a steam-outlet therefrom through the side of the Vessel near its top, the

lower end of Which passage opens Within the vessel near its bottom and the upper end above and Within the inner Wall of the annular channel, and a cover provided With a downwardlyprojecting flange to fit Within the channel and with means to close the upper end of said passage When the cover is in proper position upon the vessel.
